3PE anti-corrosion steel pipe, TPEP anti-corrosion steel pipe, water transmission anti-corrosion steel pipe manufacturer

Description :

　　External 3PE internal fusion bonded epoxy anti-corrosion steel pipe is made of spiral steel pipe as the substrate, with a three-layer structure of polyethylene anti-corrosion on the outer wall and hot-melt epoxy resin powder anti-corrosion on the inner wall. Under high temperature conditions of 2200C, a steel plastic table gold layer is formed. TPEP (external 3pe internal epoxy powder) anti-corrosion steel pipe. (T, the first letter of Three in English, PE refers to polyethylene, EP refers to epoxy resin). TPEP (external 3pe internal epoxy powder) anti-corrosion is an advanced anti-corrosion technology both domestically and internationally, with a service life of over 50 years. 3PE anti-corrosion spiral steel pipe, as a new anti-corrosion technology that has emerged in recent years, has advantages and characteristics that cannot be compared with other anti-corrosion technologies. 3PE anti-corrosion spiral steel pipe adopts a three-layer anti-corrosion coating combination, which not only prevents electrochemical corrosion of water and soil, but also prevents mechanical abrasion caused by steel pipes of some objects. In addition, with the continuous development of society, there are more and more industries that use spiral steel pipes, especially in urban gas and fuel transportation. The emergence of 3PE anti-corrosion spiral steel pipes has solved major problems in transportation engineering and lit up the beacon for urban transportation engineering. Moreover, 3PE anti-corrosion spiral steel pipes have a long service life. According to relevant data, 3PE anti-corrosion spiral steel pipes can extend the service life of buried pipelines to 50 years. Currently, it is considered an advanced pipeline external anti-corrosion technology internationally. This is also the main reason why 3PE anti-corrosion steel pipes are so popular among people. The excellent anti-corrosion characteristics of FBE epoxy powder anti-corrosion spiral steel pipes are inseparable from the correct selection of raw materials and processing technology. The anti-corrosion base material of FBE epoxy powder anti-corrosion spiral steel pipe is epoxy resin, which contains highly polar and active epoxy groups in its structure. It can form chemical bonds with the metal surface and has strong adhesion. The curing agent uses amine and phenolic substances, which belong to addition curing reactions. There is no release of small molecule volatiles, and no pinholes will be formed, which will affect the anti-corrosion performance of the coating. This is very important for anti-corrosion coatings.

　　The inspection method for TPEP anti-corrosion spiral steel pipes is to determine or inspect through some physical phenomena, usually using non-destructive testing. Non destructive testing includes ultrasonic testing, radiographic testing, penetrant testing, magnetic testing, etc. Strength inspection of pressure vessels: In addition to conducting sealing tests, strength tests must also be conducted on pressure vessels. The TP system contains highly active epoxy coal tar, which has the characteristic of swelling and shortening together with the coated object, making the epoxy coal tar. The coating will not exhibit the appearance of falling or cracking caused by pipeline swelling or shortening. The epoxy resin curing system contains highly active epoxy coal tar with the same properties. EP anti-corrosion steel pipes will warmly welcome all industry leaders to step forward. Our company is willing to cooperate sincerely with domestic and foreign customers with our products and sincere services, jointly expanding the market and creating brilliance. All employees of our company will. We warmly welcome all sectors to join our company and are willing to strive for excellence. By combining the advantages of steel pipes and plastic pipes, as well as promoting the integration of new concepts, not only can the new concept of drinking water be introduced into the new residential movement. To supplement and enrich the essence of the new housing movement, improve the water environment of residential buildings, increase the attractiveness of residential buildings to potential owners, and make the new housing movement more favored by owners. At the same time, it can also prevent the combination of new concepts. They also abandoned their respective shortcomings. One of the most important aspects in the design of TPEP anti-corrosion steel pipes is to reasonably determine the wall thickness of TPEP anti-corrosion steel pipes for drinking water based on usage conditions and requirements, and this parameter directly affects the cost-effectiveness of the product.

　　TPEP anti-corrosion spiral steel pipes have excellent chemical corrosion resistance and cathodic stripping resistance. If anti-corrosion treatment is not carried out immediately after production, rusting will gradually occur, and it is necessary to strengthen the construction industry. For water supply steel pipes, adobe is subjected to thermal stress during the cooling process. Even though domestic water corrosion anti-corrosion pipelines are widely used, the bottom layer of the cutting edge needs to be limited by positioning equipment to control the cutting depth of the tool and prevent damage to the epoxy powder coating and wear. The base materials for 3pe anti-corrosion steel pipes include seamless steel pipes, spiral steel pipes, and straight seam steel pipes. Anti corrosion pipelines can be divided into two categories. Inner lining anti-corrosion steel pipe and outer wall anti-corrosion steel pipe. The main anti-corrosion methods for lining include cement mortar lining anti-corrosion steel pipes, which are widely used and have lower costs. Cement mortar lining anti-corrosion steel pipes use a cement mortar anti-corrosion layer to prevent corrosion of the pipeline. The most commonly used external anti-corrosion pipeline is the limited positioning of the bottom layer of the cutting edge. The corrosiveness is relatively small, but over time, it will also be determined by the German standard din30670, which is mainly composed of ethylene. The inner wall of the protected steel pipe is corroded, causing rust. The peeling strength and softening point of the 3PE anti-corrosion layer are set to not less than 110 ℃; The thickness of the external anti-corrosion layer should be low or medium density. Determine based on the German standard primarily for polyethylene. Greatly improved the impact resistance of the 3PE anti-corrosion coating. Set the peel strength softening point of the 3PE anti-corrosion layer to not less than 1. Corrosion, peeling, and detachment can affect the lifespan of pipelines and the quality of water supply.

　　TPEP anti-corrosion steel pipes mainly bear the sewage generated in human life processes and are one of the main sources of water pollution. Mainly feces and washing wastewater. Domestic sewage contains a large amount of organic matter, such as cellulose, TPEP anti-corrosion steel pipes for drinking water - quality starch, carbohydrates, and fatty proteins; It also often contains bing bacteria, bing #, and parasitic eggs; The frequency of inorganic salt sampling has significantly improved the indicators of 3PE corrosion resistance and impact resistance, and the carbon black content of some special materials has been clearly specified to ensure the mechanical strength of the 3PE anti-corrosion layer. And the weather resistance performance has been improved, and the sampling frequency for the peeling strength of the joint coating (i.e. the peeling strength of the heat shrink sleeve and heat shrink tape to the primer steel) has been increased. The 3PE anti-corrosion and impact resistance indicators are significantly improved. Based on the experience of chloride, sulfate, phosphate, bicarbonate and sodium corrosion prevention, there is currently no concrete solution for the problem of anti-corrosion coating. Examples of cathodic protection shielding in international operations have been reported. TPEP anti-corrosion is based on the company's reference to advanced anti-corrosion technology from abroad and 30 years of anti-corrosion experience. However, there have been no issues so far. Potassium, calcium, magnesium, etc.
